Anophthalmic Socket Management

Anophthalmic Socket Management - Empty Orbit Essentials

• Anophthalmic Socket: Orbit lacking the globe.
• Common Causes:
  • Surgical Removal:
    • Enucleation: Entire eyeball removed.
    • Evisceration: Intraocular contents removed, scleral shell retained.
  • Congenital: Anophthalmos (absent eye), severe Microphthalmos (small eye).
  • Severe Trauma.
• Primary Management Goals:
  • Achieve good cosmesis and facial symmetry.
  • Ensure patient comfort, free from pain or discharge.
  • Provide adequate support for a stable ocular prosthesis.
  • Prevent socket contracture and fornix shortening.
  • Stimulate orbital development in pediatric cases.

⭐ In children, early fitting of conformers/expanders is crucial to stimulate adequate orbital bone and soft tissue growth, preventing facial asymmetry.

Anophthalmic Socket Management - Woes & Watchouts

Evaluate: Fornices, lid laxity, implant, motility.

Common Complications & Management Hints:

⭐ Volume deficiency is the primary cause of Post-Enucleation Socket Syndrome (PESS).

Anophthalmic Socket Management - Fixing the Void

• Core Goals: Restore orbital volume, ensure prosthesis motility & comfortable wear, achieve good cosmesis.

• Orbital Implants: Primary volume replacement. Sizes: Adults 18-22 mm; Children 16-20 mm.

  • Implant Types:

    Type	Material	Advantages	Disadvantages
    Non-porous	PMMA, Silicone	Inexpensive, smooth	↑Extrusion/migration, ↓Motility
    Porous	Hydroxyapatite, Porous PE (Medpor), Alumina	Fibrovascular ingrowth, ↑Motility, pegging possible	Costly, exposure risk, needs wrapping (e.g., sclera, fascia lata)

• Dermis-Fat Graft (DFG): Autologous graft for severe volume deficit, contracted sockets, or when implants fail/extrude. Provides vascularized volume. Harvest: lateral buttock/thigh.

• Volume Augmentation Strategy:

• Socket Health: Maintain adequate fornices for prosthesis. Address lid malpositions (ptosis, ectropion).

⭐ Post-enucleation socket syndrome (PESS) includes enophthalmos, deep superior sulcus, ptosis, and lower lid laxity due to volume issues or implant problems.

Anophthalmic Socket Management - The Perfect Fit

• Goal: Restore orbital volume, cosmesis, support eyelids.
• Prosthesis Types:
  • Stock: Temporary, less ideal fit/motility.
  • Custom (PMMA): Impression-molded; optimal fit, aesthetics, motility.
• Fitting Process:
  • Conformer post-op (prevents socket contraction).
  • Impression after 4-6 weeks healing.
  • Custom prosthesis fitted for comfort & symmetry.
• Patient Care:
  • Daily cleaning (mild soap).
  • Professional polishing q 6-12 months.
• Common Issues:
  • Discharge: Hygiene, infection check.
  • Socket Contraction: Conformers, surgery if severe.
  • Giant Papillary Conjunctivitis (GPC): Prosthesis hygiene, polishing, topical agents.

⭐ Custom ocular prostheses offer superior motility and natural appearance due to precise, individualized socket fit.

High‑Yield Points - ⚡ Biggest Takeaways

• Socket contraction prevention is key post-enucleation/evisceration.
• Immediate conformer use maintains forniceal depth and socket shape.
• Porous implants (hydroxyapatite, polyethylene) improve prosthesis motility via fibrovascular ingrowth.
• Post-Enucleation Socket Syndrome (PESS): deep superior sulcus, ptosis, enophthalmos, lower lid laxity.
• Volume augmentation (implants, dermis-fat grafts) is crucial for PESS and prosthetic fit.
• Strict socket hygiene prevents discharge, infection, and giant papillary conjunctivitis (GPC).
• Implant exposure management: conservative, patch grafts, or explantation.
